Usage

Sika® Facade Baffle is used as part of open-drained joints in precast concrete façades. The baffle, inserted into preformed cavities in the vertical joints of the precast panels, prevent direct entry of most of the wind-driven rain. Sika® Facade Baffle is used in conjunction with Sika sealants and expansion tapes. These sealants and expansion tapes are used to provide an air seal at the interior face of the precast panels to prevent any water that gets past the baffle penetrating into the building. The thickness of the Sika® Facade Baffle is sufficient to resist deforming and vibrating under wind load.
